When Will a Coronavirus Vaccine Be Ready? Early Human Trials Show “Encouraging” Results


Massachusetts biotechnology company Moderna appears to be leading the way in its effort to create a vaccine for the coronavirus.

In fact, their stock soared “as much as 39% to record highs in early Monday trading” according to Business Insider amidst encouraging results from their early human trials.

Eight participants who were given “low and medium doses of Moderna’s vaccine had blood levels of virus-fighting antibodies that were similar or greater than those in recovered COVID-19 patients,” the Washington Post reported. “That suggests, but doesn’t prove, that it triggers some level of immunity.”

Another 17 people in the trial had an immune response that registered at a level similar or greater than patients who’ve recovered from COVID-19. However, scientists haven’t yet tested if the antibodies they produced actually neutralized the coronavirus.

Companies and countries across the world are in a race to create a vaccine that can be mass distributed as soon as possible. But vaccine experts have noted that while accelerated timelines are theoretically possible, they are “extremely optimistic,” as so many phases are required before a vaccine is safe to be distributed to the public.

NBC medical correspondent Dr. John Torres elaborates on the vaccine phases and projected timelines in a TODAY interview with Hota Kotb.

“This is good news because we’re getting steps forward in the vaccine process here, but [Moderna] still has two more phases to go through,” said Torres. “They’ll do a phase 2 which is about 600 people, and then they’ll do a big phase 3. They think they’ll start that one in July. That’s the one that’s gonna give us a lot of answers. If they get through that, then we’ll get the vaccine; keeping our fingers crossed.”

So what does that mean in terms of when the public will be seeing a vaccine available?

That’s the question that’s even tougher to answer with certainty.

“That usually takes months or years—in this case, they’re hoping months, so again I think that 12-18 month is probably somewhat expected,” remarked Torres. “So we’re talking sometime after the new year I think is when we’ll get it. Maybe before if things fall into place really well.”

Another point worthy of note regarding the early vaccine phase for Moderna was brought up by Daniel Salmon, Director of the Institute for Vaccine Safety at the Johns Hopkins Bloomberg School of Public Health.

“I would certainly take this as good news, and it’s certainly worth moving forward” into later-stage trials, said Salmon. “There’s just historically, if you look at vaccine development, lots of vaccines that look good out of Phase 1 that don’t turn out to be good products.”
